Microbes and us: microbiology literacy in Greece

Microbes are ubiquitous and provide numerous services to humans and our planet. However, a query arises as to whether these microbial services are valued by the general public especially after unprecedented conditions like the COVID-19 pandemic. In this context a survey was conducted to investigate the concept of microbe in Greece. Thematic analysis of 672 anonymous responses (age range 4-75yo) received for the open-ended prompt "What is the first thing that comes to mind when you hear the word microbe?" revealed five thematic categories: Negative emotions, Fuzzy associations, Biology, Entities and Health. Almost 80% of responses fell under "Biology" and "Health" and the general pattern of answers was the same across all age groups. Microbes took a variety of forms in the minds of respondents, however, the concept of "microbe" seems to be more unshaped at younger ages (4-11yo), as revealed in children's language choices. Overall, the often-negative perception of microorganisms seems to be confirmed in this study. Although this research was limited to participants from Greece, it remains relevant to other countries around the world as well. We discuss the reasons behind this negative perception and offer suggestions for reversing it.
